报错： Consecutive statements on a line must be separated by ‘;’

有一种报错叫做：Consecutive statements on a line must be separated by ‘;’

有各种各样的原因。。比如。。

1.三目运算符的?和>的前面没加空格

let a = 4 > 3 ?"yes" : "no"

1	let a = 4 > 3 ?"yes" : "no"

2.末尾多加了一个半括号

3.数组写成了花括号{}

改成：

var a = ["1", "2", "3"]

1	var a = ["1", "2", "3"]

4.比如 as 后面多加了个‘!’都会被这个报错。。
